Defending against speculative attacks – It is risky,but it can pay off

While currency crises are typically considered to be painful and costly events, a closer look reveals that economic developments after a speculative attack differ considerably. Monetary authorities can play a central role in determining the economic course and costs of currency crises. They have to decide whether to defend or not to defend the domestic currency giving rise to three different types of crises: (i) an immediate depreciation if the central bank does not intervene and either (ii) a successful defense or (iii) an unsuccessful defense in the case of an intervention. We find that a central bank has two options to mitigate the costs of speculative attacks, namely an immediate depreciation and a successful defense. If a central bank intervenes she might be able to stabilize the exchange rate only temporarily and risks to ultimately fail facing the worst of the three scenarios with the highest economic costs.     

To intervene,or not to intervene: Monetary policy and the costs of currency crises

In case of speculative attacks, the central banks' decisions to intervene or not to intervene seem to play an important role for the economic costs of currency crises. The central bank can either abstain from intervening or start an intervention, which in turn can be successful or unsuccessful. Therefore, an adequate analysis of the costs of currency crises has to take into account three different types of currency crises: (i) an immediate depreciation without any central bank interventions, (ii) a successful defense, and (iii) an unsuccessful attempt to defend the exchange rate. We find that the decision of the central bank to intervene or to remain passive is risky. If the central bank intervenes and succeeds she can achieve the best growth performance on average. However, if the interventions are not maintained and the currency depreciates the subsequent output loss is particularly severe. Abstaining from an intervention yields a scenario with a relatively small drop in output. Giving in to a speculative attack rather than trying to fight it can thus be a suitable option for a risk-averse central bank.     

Economic uncertainty and the influence of monetary policy

This paper explores if economic uncertainty alters the macroeconomic influence of monetary policy. We use several measures of U.S. economic uncertainty, and estimate their interaction with monetary policy shocks as identified through structural vector autoregressions. We find that U.S. monetary policy shocks affect economic activity less when uncertainty is high, in line with “real-option” effects from theory. Holding uncertainty constant, the effect on investment is approximately halved when uncertainty is in its top instead of its bottom decile.     

Speculative attacks: A laboratory study in continuous time

We examine speculative attacks in a controlled laboratory environment featuring continuous time, size asymmetries, and varying amounts of public information. Attacks succeeded in 233 of 344 possible cases. When speculators have symmetric size and access to information: (a) weaker fundamentals increase the likelihood of successful speculative attacks and hasten their onset, and (b) contrary to some theory, success is enhanced by public access to information about either the net speculative position or the fundamentals. The presence of a larger speculator further enhances success, and experience with large speculators increases small speculators' response to the public information. However, giving the large speculator increased size or better information does not significantly strengthen his impact.     

The impact of monetary policy on the exchange rate: A high frequency exchange rate puzzle in emerging economies

This study investigates the impact of monetary policy shocks on the exchange rates of Brazil, Mexico and Chile. We find that even a focus on 1 day exchange rate changes following policy events – which reduces the potential for reverse causality considerably – fails to lend support for the view that associates unexpected interest rate hikes with immediate appreciations. This lack of empirical backing for the predictions of standard open economy models persists irrespective of whether we use the US Dollar or effective exchange rates, whether changes in the policy rate that were followed by exchange rate interventions are excluded, whether “contaminated” events are dropped from the analysis or whether we allow for non-linearities. We argue that it is difficult to attribute this stronger version of the exchange rate puzzle to fiscal dominance, as unexpected rate increases are not associated with increases in risk premia, and similar results are obtained in the case of Chile – a country that has had the highest possible short-term credit rating since 1995 and a debt/GDP ratio below 10%.     

Valuation impact of currency crises: Evidence from the ADR market

This study analyzes American depository receipts (ADR) performance surrounding the outbreak of major currency crises during the past decade. By employing event-study methodologies and multifactor pricing models, we find that the outbreak of a currency crisis is accompanied by a negatively significant abnormal return for the corresponding ADRs, even after controlling for variations in exchange rates. We also find significant upward shifts in the exchange rate exposure of ADRs when the home currency is switched from a “pegging” to a “floating” exchange rate regime. In addition, ADR-originating firms with larger sizes, greater proportions of U.S. market activities, and greater market liquidity have relatively less negative abnormal returns (ARs) and less significant upward shifts in currency exposure, implying that such firms are relatively better hedged against currency crises.     

The discrete and differential impact of monetary policy

This study exploits a unique feature of the Australian monetary policy environment to determine whether economic recovery can be stimulated via central bank communications. This study finds that unexpected monetary policy announcements and communications have a significant and comparable impact on the value and volatility of the Australian foreign exchange market, suggesting that they can be used interchangeably to stimulate economic recovery. However, further analysis reveals that the state of the economy influences this impact. Specifically, during poor economic states, monetary policy actions speak louder than words, an adage that in this context provides actionable information for central bank regulators.     

The impact of monetary policy announcements on the stock price of large European banks during the financial crisis

Since 2007, the European Central Bank responded decisively to the challenges posed by the global financial crisis, reducing key policy interest rates to unprecedented low levels and intervening with non-standard policy measures (i.e., monetary easing and liquidity provision). This paper aims to assess the impact of ECB monetary policy announcements on the stock price of large European banks. As a first step, an event study is conducted in order to measure cumulated abnormal returns (CARs) around the announcements over June 2007–June 2013; the second step is a regression analysis aimed at identifying the determinants of CARs. Results show that banks were more sensitive to non-conventional measures than to interest rate decisions, and that the same type of intervention may have a different impact depending on the stage of the crisis. In addition, banks with weaker balance sheets and operating with high-risk were more sensitive to monetary policy interventions.     

Spillover effects from Euro area monetary policy across Europe: A factor-augmented VAR approach

I analyze spillover effects from a Euro area monetary policy shock to fourteen European countries outside the Euro area. The analysis is based on a factor-augmented VAR model with two blocks, which exploits a large cross-country data set. After a Euro area monetary policy expansion, production increases in most non-Euro area countries, whereas short-term interest rates and financial uncertainty decline. These effects are on average comparable to the responses in the aggregate Euro area. However, the size of spillover effects varies with country characteristics. Spillovers on production are larger in non-Euro area economies with higher trade openness, whereas financial variables react to a higher extent in countries with higher financial integration. Regarding the exchange rate regime, countries with fixed exchange rates show stronger spillovers both in terms of production and interest rates. Finally, prices increase in Western European economies outside the Euro area, but decline or do not respond in Central and Eastern Europe.     

Narrative and VAR approaches to monetary policy: Common identification problems

Romer and Romer [Romer, C.D., Romer, D.H. 1989. Does monetary policy matter? A new test in the spirit of Friedman and Schwartz. In: Blanchard, O.J., Fischer, S. (Eds.), NBER Macroeconomics Annual 1989. MIT Press, Cambridge, MA, pp. 121–170; Romer, C.D., Romer, D.H., 1994. Monetary policy matters. Journal of Monetary Economics 34, 75–88] adopted a narrative approach to address the identification problems in time series models of monetary policy. Based on Federal Reserve documents, the Romers created a dummy variable equal to one in periods when the Federal Reserve contracted in response to perceived inflationary pressures. This paper shows: (1) the dummy variable is predictable from past macroeconomic variables, reflecting the endogenous response of policy to the economy; (2) unpredictable changes in the dummy do not generate dynamic responses that look like the effects of monetary policy. The identification problems that plague time series models also afflict the narrative approach.     

Futures prices as risk-adjusted forecasts of monetary policy

Many researchers have used federal funds futures rates as measures of financial markets’ expectations of future monetary policy. However, to the extent that federal funds futures reflect risk premia, these measures require some adjustment. In this paper, we document that excess returns on federal funds futures have been positive on average and strongly countercyclical. In particular, excess returns are surprisingly well predicted by macroeconomic indicators such as employment growth and financial business-cycle indicators such as Treasury yield spreads and corporate bond spreads. Excess returns on eurodollar futures display similar patterns. We document that simply ignoring these risk premia significantly biases forecasts of the future path of monetary policy. We also show that risk premia matter for some futures-based measures of monetary policy shocks used in the literature.     

The impact of conventional and unconventional monetary policy on investor sentiment

This paper examines the relationship between monetary policy and investor sentiment across conventional and unconventional monetary policy regimes. During conventional times, we find that a surprise decrease in the fed funds rate leads to a large increase in investor sentiment. Similarly, when the fed funds rate is at its zero lower bound, research results indicate that expansionary unconventional monetary policy shocks also have a large and positive impact on investor mood. Together, our findings highlight the importance of both conventional and unconventional monetary policy in the determination of investor sentiment.     

Stock market reactions to monetary policy surprises under uncertainty

This article investigates how uncertainty impacts the effect of monetary policy surprises on stock returns. Using high-frequency US data, we demonstrate that stock markets respond more aggressively to monetary policy surprises during periods of high uncertainty. We also show that uncertainty asymmetrically influences the transmission of positive and negative monetary policy surprises to stock market prices. The amplifying effect of uncertainty is found to be stronger for expansionary shocks than for contractionary shocks. Our robustness analysis confirms that financial uncertainty has a significant role in shaping the influence of monetary policy on the stock market.     

Banks,maturity transformation,and monetary policy

Banks engage in maturity transformation and the term premium compensates them for bearing the associated interest rate risk. Consistent with this view, I show that banks’ net interest margins and term premia have comoved in the United States over the last decades. On monetary policy announcement days, bank equity falls more sharply than nonbank equity following an increase in expected future short-term rates, but also responds more positively if term premia increase. These effects are reflected in bank cash-flows and amplified for banks with a larger maturity mismatch. The results reveal that banks are not immune to interest rate risk.     

The timing of exchange rate collapse

Recent episodes of exchange rate collapse have renewed interest in models of speculative attacks. These episodes have been considered by some observers to be inconsistent with “fundamentals” models of attack since there was no prolonged period of policy misalignment and declining reserves, as required by such models. This paper develops a fundamentals model in which collapse is instantaneous at the time of unexpected policy change and/or a change in the expectations of future policy, even for a reserve abundant country.     

Endogenous objectives and the evaluation of targeting rules for monetary policy

Recent research in monetary economics has followed the advice of McCallum [1988. Robustness properties of a rule for monetary policy. Carnegie-Rochester Conference Series on Public Policy 29, 173-203] and investigated the robustness properties of monetary policy rules by evaluating them in a variety of models. Evaluation across models is typically based on an exogenously specified loss function. However, the theory on which many recent monetary policy models are based implies that changes in the structure of the model also have consequences for the policy objectives the central bank should pursue. Objectives are endogenous, not exogenous to the model. In this paper, I investigate the impact of endogenous objectives on the evaluation of targeting rules for monetary policy.     

Loss aversion and the asymmetric transmission of monetary policy

There is widespread evidence that monetary policy exerts asymmetric effects on output over contractions and expansions in economic activity, while price responses display no sizeable asymmetry. To rationalize these facts we develop a dynamic general equilibrium model where households’ utility depends on consumption deviations from a reference level below which loss aversion is displayed. State-dependent degrees of real rigidity and elasticity of intertemporal substitution in consumption generate competing effects on output and inflation. Contractions face the Central Bank with higher responsiveness of output to interest rate changes, as well as a flatter aggregate supply schedule.     

International interest rates and US monetary policy announcements: Evidence from Hong Kong and Singapore

This paper investigates the responses of market interest rates to US monetary policy announcements for the US and two emerging economies, Hong Kong and Singapore which are similar on many respects but have experienced opposite exchange rate regimes in the last twenty years. Our results, based on market expectations extracted from federal fund futures rates, document that FOMC announcements significantly affect the term structure of interest rate in the US and both Asian countries. Further, international interest rate differentials around FOMC meeting dates tend to be negative for short maturities with the impact gradually dissipating as bond maturity increases. Finally, for the case of Singapore, we find that domestic interest rates react to both external and domestic monetary policy announcements with a magnitude that is larger over the full bond maturity spectrum for domestic announcements. These results are robust to time-varying futures risk premia and alternative measures of interest rates expectations.     

经济增长、结构失衡与流动性过剩——论我国当前流动性过剩的成因与对策

由于社会保障制度的不完善和分配结构的不合理,经济增长带来居民收入增长的同时,消费需求难以有效放大,储蓄和净出口的高增长成为必然。储蓄的高增长导致银行的存贷差上升,其分流导致股市和房市的流动性过剩;净出口的持续高增长和国际资本的大量涌入导致国际收支持续的高顺差。由于汇率缺乏弹性,基础货币的被动增加和货币乘数的预期外上升一并导致货币供给过剩。强化储备货币发行国的发行约束;调整外贸发展战略,优化产业结构;扩大消费需求;扩大汇率浮动区间;提高货币政策的科学性等措施可以有效控制和利用流动性过剩。     

Learning and the monetary policy strategy of the European Central Bank

This paper examines the welfare implications of alternative inflation targeting proposals for the monetary policy of the European Central Bank. We assume that policy makers have to “learn” the laws of motion of inflation in an economy characterized by “stickiness” in domestic price setting behavior and subjected to recurring shocks to productivity, exports and foreign price. We find that a switch from an “asymmetric” inflation targeting strategy to an “symmetric” makes little difference in welfare payoffs, but it comes at a cost of much higher interest-rate variability. We also find that there are practically no welfare gains from switching from an inflation-targeting strategy based on the Harmonized Index of Consumer Prices (HICP) to a strategy based on the domestic price component of the HICP.
